Fossils with MOP Update

[stevecrocker]

I know nothing about these except that I dug them up at the Cooper Lake Project in east Texas in 1989.They seem like some sort of fish spine
Here is a picture of a three piece fossil but doesn't have the pearlized stuff on it.Dug at the same project in 1989.
UPDATE............

The three piece has been sold but the pearlized two piece is still available.....Email me....Serious only please...

they are bacculite fossils. bacculites were straight shelled ammonoids or mollusks. very nice ones too! if you ever wanna trade or sell one...please let me know.

I love the pearly finish on the baculites....
